Abstract

21 species foraminifera, including in 14 genera were encountered from 39 samples of core PC10, which were drilled in the Bransfield Strait of Antarctic Peninsula. They are divided into 3 assemblages as follow: 1. Siliceous shell assemblage; 2. Calcareous shell assemblage; 3. Mixed shell assemblage. The Siliceous shell assemblage occurred in normal deep-sea, with weaker water dynamic condition. The Calcareous shell assemblage was formed by turbidity flow, while the Mixed shell assemblage represented intense to weaker water dynamic condition. It changed from warm to cold to warm during the late Quaternary.
